Be it known that I, DAVID JAFFRAY, of

' Chicago, in the county of Cool; and 'State of Illinois, have inventedeertainnewand useful Improvements in Horseshoes; and I do hereby declarethat thcfollowing is a full, clear, and exact description thereof',reference being had to the accompanying drawings, and tothe letters ofreference marked thereon, which form a part of this specification.

This invention relates to an improvement in that class of ,horseshoes.consisting oi' a part which is attached permanently tothe horses foot,-and a second removable part which is attached to the permanent part insuch manner that it may be readily removed for the purpose of repairingor rcplaci ng calks attached thereto, or for other purposesu The objectsof this invention are to provide an improved means for detachablyconnecting the parts of atwopart horseshoe, and for securing calks insuch shoes; and it consists in the matters hereinafter described, andpointed ont in the claims.

In the accompanying drawings, Figure lis a perspective view of a horsesfoot and a two-part shoe of 4a form proposed by my invention attachedthereto. Fig. 2 is a similar view of the part of the shoe which isperina-- neatly attached to the foot. Fig. 3 is a perspective view ofthe removable part of the shoe detached. Fig. 4f is a plan view showinganother form of the same. Fig. 5 is a fragmentary sectional view ofthetwo parts lof the shoe, and of adjacent portions ot the hoof, taken uponline xm of Fig. 4. Figa 6 is a `similar sectional view taken uponlineje/ y of Fig. 4. Fig. 7 is a detail view, which will be hereinafterdescribed.

A is the inner or stationary part of the shoe, which is attached bymeans of nails, in the usual manner, to the hoof, and is intended to beremoved only at such times as it be comes necessary on account of thegrowth of the hoot.

B is the outer or removable partof the shoe, which is made ot' the samesize as the part A, and preferably fiat upon its upper surface, so as tolit `open the corresponding :dat lower snrfacc of the part A., 'andispreferably provided With removable calks C, secured thereto in a mannerhereinafter described.

As an improved means of removably securing the part B to the part A, thecurved portion at the front or toc end of the bar, comprising the partA, is ont ofi' transversely, so

as to form a straight face, a., and the rea-r ends of its side portionsare made slightly shorter than the corresponding portions of the part B,and are formed with transverse end faces, a', in alignment with eachother and generally parallel with the face a. The opposite faces ca',above mentioned, are beveled downwardly and outwardly, as shown in Fig.2, and the part B of the shoe is provided at its front and vso that whenthe two parts of the shoe are placed together bybeing slipped or movedsidewise, one upon the other, there will be no tendency of the plates tobecome loosened' by a slight relativelateral movement.

Instead of making the faces of the projections B and Bl and the faces ofthe part A engaged therewith inclined or beveled, las above described,the same result may obviously be effected by providing the parts withinterlocking projections of other shape, as is, for instance, indicatedin the detail View, Fig. 7, in which a part of the rear ends of theparts of the shoe are shown as provided with interlocking rectangularprojections ci and 11".

The plates,when held together in the manner above descrbed,may be heldfrom lateral movement by a pin, D, inserted through ap ertnres ai and Ilin the plates A and B, respectively, or in any other well-known or dcsircdmanner.

As illustrated in Figs. l, 2, and 3 the parts of the shoe are heldltogether by the pin D only; butin the form oiI the shoe illustrated IOOportion, b5, surrounding the aperture B3.

in Fig. 4t the projections B and BI are provided with stops b4 to limitthe relative lateral movement-of the plates in one direction, the pin Dbeing depended on to hold the plates from movement in a direction awayfrom the stops only. The pin D, as shown more clearly in Fig. 5, ispreferably located at one side of the shoe, and adjacent to the outeredge of the bars or plates comprising the latter, a small notch', E,being preferablycut in the hoof at a point adjacent to the upper end ofthe pin, whereby a punch or other implement may be vapplied for drivingout the pin. W'hen stops b4 are used,they are preferably placed upon theside of the shoe which is located at the inner side of the hoof, so thatthe part B of the shoe may be slipped in place from the outer sidethereof; and the pin D is preferably located at the same or outer side,so as to be readily accessible to the operator. rIhe calks C are, asherein shown, provided with enlarged portions or heads c, and insertedin apertures B in the part B of the shoe, thc head c being countersunkor fitted in recesses in the shoe, so as to be flush with the uppersurface thereof, and to rest against the lower surface of the part Awhen the parts of the shoe are placed together. The walls of theapertures B3 are preferably made parallel, as shown more clearly in Fig.6,v and the portion of the calks located within the apertures ofcorresponding shape, the object of this construction being to preventany slight end movement of the calks from loosenr ing them, as is liableto be the case when the body ofthe calks is tapered, as in aconstruction heretofore used in a two-part shoe. As illustrated in Figs.l, 3, and 6,three calks are used, the portion of the shoe adjacent tothe toe-calli being shown as 11e-enforced by a raised In Fig. 4 thc partB is represented as being provided with apertures for four calks. Anydesired number of calks may, however, be used, and they may be arrangedin any desired or preferred manner. l

An important advantage in the construction in the means for connectingthe two parts of the horseshoe above described is that the projections Band B2, being arranged transversely of th'e shoe, are in a position tomore effectual] y resist the strains having the greatest tendency toseparate the parts ofthe shoe.such strains being those produced by thepull or strain caused by-the efforts of the horse todraw the load andthose caused by the'contact of the shoe with stones or the ground whenthe foot is thrown forward.

Another advantage derived from the construction set forth is that thecalks are firmly and securely held iuplace, and may be quickly andreadily removed and replaced or new ones inserted.

Other advantages arethat the parts being .exceedingly simplein/construction they may be easily manufactured to t to cach other, itbeing possible, on account of the simplicity of the structure in thelower and movable parts, to malte it of cast-steel,whereby :it will bemuch stron ger and Inoredurable than when forged of iron in the usualmanner. By mal;-

ing the projections B' and B2, by which the upper and lower parts areconnected, upon the lower part, the upper part or plate attached to thehoof is left perfectly plain and flat upon its lower side, so that whenthe lower or detachable part is removed the horse may rest upon the saidupper part without injury thereto, and the said upper part `beingcomparatively lightr and thin, the horse is practically sh oeless whenthe said lower part is removed.

A great benefit may be obtained by removing the lower part when thehorse becomes lame or is to stand some time without use, the foot, onaccount of the thinness of the plate, being permitted to rest upon theground in the natural manner and with the frog in contact therewith.

Itis found advantageous to removethe lower part of the shoe, containingthe calks, when the horse is to stand for some time, for the reason,also, that the liability ofthe horse to strike and injure himself withthe calks is thereby avoided.

I 4am aware that two-part horseshoes have dovetailed projections uponone part which entercorrespondingly -shaped recesses in an-y other part.The appended claims are vnot therefore i intended to cover, broadly,such dovetailed connections; but my invention is limited to aconstruction in which one plate or part vcomposing the shoe is flat,andfis provided with transverse end faces constructed to interlock withtransverseprojections upon the other part, as set forth in the followingclaims.

I claim as my invention l. The combination, with the stationary part Aof a two-part horseshoe having transverse end faces, of a removablepart, B, provided with projections B B2, having transverse inner facesconstructed to interlock with the end faces of the part A, and meansconstructed to secure the parts A and B fromlateral movement,substantially as described.

2. The combination, with the parts A and B of a horseshoe provided,respectively, with transverse interlockingfaces, of stops b, constructedto hold the parts from movement in one direction, and means forholdingthe parts from movement in the opposite direction, substantially asdescribed.

In testimony that I claim the foregoing as my invention IaffiX mysignature in presence of two witnesses.
